Since invasive species did not co-evolve with the other species in the ecosystem where they were introduced . a. they can unbalance the ecosystem b. they are considered a serious environmental problem c. they lack natural predators to help control their population d. all of the above

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.

what? are the statements?

answer; aerobic conditions; citric acid cycle (krebs cycle) electron transport chain;         anaerobic conditions; fermentation; both glycolysis;
